How does swim extract sildenafil from Viagra?

[xspikehead]

Swim would like to know if there has been any established procedure to extracting out Viagra's active ingredient, because the weight of the active ingredient is far less than that of the entire pill, and he doesn't want the filler.  Would extracting it by Straight to E by VideoEditor possibly work?

Solubility: 3.5 mg/ml in water

Most of the filler are insoluble in water, so simply crush the pill, then pour water on. Let the mix for about one hour or 2, stir sometimes, then filter. The Sildenafil is in the water, evap the water to get the Citrate (MP: 190-193°C)

no, just kidding...

I read a lot since i am here. So you have to do it too. Like everyone here in to.
I read, that nearly every Pill-Extraction work for nearly every Pill.
Why?
You have a the material in the pill. The material is "around" the pill, we could say "coated with shit". Wash this shit away and you got the material which is under the coat...

get it??


If that dont work, try, read, try, read, try........

Blind_Angel, thank you for your help, I greatly appreciate it.
Gringo, why are you assuming that I haven't done my required reading?  If you will refer back to my first post on this subject, you will see that I questioned if a  pseudoephedrine extraction technique would be appropriate.  And your explanation of the distribution of contents in a pill is a generalization at best, and certainly not of any help to anyone here.  Perhaps you should do more reading before making the incorrect assumption that I haven't, or that I don't know the techniques.

BTW....

Swim is going to discard the sildenafil after he spends a great deal of time and effort extracting it.

down my friend...

no need to get an attitude...

curiosity is that thing that leads to this place...

.....Swim tried an Pill extraction, but it wasnt as good as he hoped, so he tried on, read on, etc...
with no further progress... its just the KNOWLEDGE which is interesting for swim, not the gossip around it...

anyway gossip is conspicous, BUT necessary...
